You write the hotkeys by its Hex code example: 0x04
Very Important!
The application is very "load" sensitive. That meaning if your hotkey dont work or stop working you have to press load once or twice for them to work again.
For example NoClip bugs sometimes and wont deactivate. This happens if you have fly on and then replace it with speed. Then you have to press load for the hotkey to deactivate noclip works again so you dont repetedly fall through the ground dying over and over
Side Mouse Buttons dont work at all. Those being xbutton1 and xbutton2, Hex codes 0x06 and 0x05.
Hope this helps

A special thanks to the person that helped me figure this out <3
